5:31Then God sent a raven digging the ground, to show him how to cover his brother's corpse. He said, “Woe to me! I was unable to be like this raven, and bury my brother's corpse.” So he became full of regrets.

5:36As for those who disbelieve, even if they owned everything on earth, and the like of it with it, and they offered it to ransom themselves from the torment of the Day of Resurrection, it will not be accepted from them. For them is a painful punishment.

5:108That makes it more likely that they will give true testimony, fearing that their oaths might be contradicted by subsequent oaths. So fear God, and listen. God does not guide the disobedient people.

5:115God said, “I will send it down to you. But whoever among you disbelieves thereafter, I will punish him with a punishment the like of which I never punish any other being.”
